To col? whom, it may concern:

Belt known that I, WILLIAM N. CRABTREE, a cltizen ofthe United States, and a resident of Globe, in the county of Tulare and State of California, have invented certain new and useful Improvements in Bandage-Rollers for Surgeons; and I do declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a front view of the invention, showlng a roll of bandage thereon. Fig. 2 is Fig. 3 is a perspectlve vlew of the invention with spool removed, and the stirrup up. Figs. 4 and 5 are details of disk on end of hollow shaft. Fig. 6 is a side elevation of axis K and disks. Fig. 7 shows the guide. Figs. Sand 9 are modifica tions of spool. Fig.10 is a perspective view of the band hook. Fig. 11 is a detached, per-.

spective view of the stirrup.

This invention has relation to certain new and useful improvements in bandage rollers for surgeons, the object being to provide a device of this character, simple in its construction, convenient in the manner of its operation, and which will completely meet the wants of the surgeon in an instrument of this sists in the novel construction and combination of parts, all as hereinafter described and pointed out in the appended claims.

Referring to the accompanying drawings,

' the letter A designates the frame of the device, having centrally attached to one edge thereof a suitable handle A, and having its end portions bent upwardly at substantially right angles to formvertical arms a, a. In the arm a is formed an open bearing b, which receives one of the journals of the spoolB, while the arm a has a bearing therein for. a short shaft oraxis O, to which is attached a crank O, and which at its inner end is formed with a transverse slot 0, which receives a transverse arm 01, on the corresponding end.

of the spool shaft. To place the spool in the frame it is necessary to first place the arm at in engagement with the said slot 0, the oppois swung to one side.

,site end portionor journal ofthe spool shaft being then inserted in the open bearing 12. The engagement of the arm at and slot 0 provides means whereby thelrotation of the crank O is communicated to the spool, while permitting the spool tobe readily inserted and removed.

D designates a stirrup-shapedxframe, the

vertical arms of which are pivoted to the arms a, a at the points d, d, the horizontal portion of the stirrup as itwill hereinafter be termed, being underneath the horizontal arm of the frame A. The said horizontal portion of the stirrup is cut-away or of slotted form, the swinging motion of the stirrup being limited by the engagement of the slot with two set screws E, E. These set screws also serve to adjust respectively a pair of bandage guides F, F,which are made adjustable in longitudinal slots f, f, in the horizontal arm of the frame A at the sides thereof opposite the handle A. These guides have two-part clamps f, which are arranged to engage with and slide in the said slots, and engaged by said set screws, whereby they may be adjusted to the width of the bandage.

One of the vertical arms of the stirrup has an extension g", which forms a keeper for that end of the spool shaft which engages the open bearing b, and prevents the spool from being removed except when the stirrup The spool may be of several different forms, as will now be described.

In Fig. 9 I have shown a spool which consists simplyof a tapered rod having the arms or projections d at one end portion for engagement with the crank axis, and a small projection 71. at its central portion for engagement with the bandage to hold it when the formation of the roll is commenced. This form of spool is employed when the surgeon desires to roll a bandage, or several of them, for immediate use, and may be Withdrawn after the roll is removed from the winder.

Fig.8 shows a second form designed to retain the roll for use, and having circular flanges or disks H, near each end between which the bandage is rolled.

Fig. 1 showsa more complete form of spool, comprising a hollow shaft J, having at each end a circular flange or disk J This hollow. shaft receives an axis K, which near each end carries a disk K ,similar to the disks J, and fitting against the said disks. inner face of each disk K, the axisK carries a short arm j, which terminates in a cam shaped head j, arranged to engage with a cavity is in the body portion of a hook device 'L'. This book device is seated between the two disks J, K, the former being partially cut away to receive it, and is pivotally secured to said disk K at k. At one end the axis K has pivotally secured therein .a lever M, which takes the place of the armsor projections of in the other forms of spool, being arranged to engage with the crank axis. One arm of this lever carries a spring m, which bears against the outer face of the disk K, and throws the opposite arm of the lever against the disk causing a projection or stud n thereon to engage with a small aperture or cavity n in the said disk, locking the hook devices in such position that their points do not protrude from between the disks. By

pressing upon the spring-carrying arm of said lever, theprojection or; may be withdrawn from said aperture n. The axis K now being slightly rotated, by means of the lever M, the cam arms j take a bearing against thehook devices, moving them sufliciently to cause their hooks to project from between the disks. An opposite rotation of the shaft again withdraws said hooks. By engaging the bandage with either one of these hooks it maybe temporarily held from unwinding while thesurgeon is fixing splints, or otherwise engaged.

V P designates a band hook, which may also be employed for holding the bandage, said hook comprising a piece of metal, having hooks p for engagement with the windings of the band upon the spool.

' In order to facilitate the introduction of the axis'K into the spoolit is made in two sections, the adjacent ends of the said sections being formed one with an angular tongue r, and the other with a corresponding socket r, to receive said tongue'and thus unite the two sections.

To spool a bandage with any of the forms of spools above described, place the spool in the winder while the stirrup is swung up, pass the bandage through the slot in the stirrup between the two guides. Then close the stirrup down. The bandage is then made fast to the spool, and the crank rotated.

, Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent,- is I I 1. In a bandage roller for surgeons, a frame, having open bearings thereon, a spool arranged to removably journal in said bearings, adjustable bandage guides working in said frame, and a stirrup device pivoted to said frame and arranged to temporarily'con- 3 fine the spool in its bearings, substantially as 1 specified.
